I have a question that may seem a bit weird. Yesterday I was shopping at Nordstrom with my girlfriend. Some pretty good items on sale. A saleswoman (thought it was weird that there were all Men sales staff at the Women's side, and all Women at the Men's side, except for the shoe area) caught me checking out some of the various suits on display. She asked if I'd like to be measured. I said, sure, why not. She proceeded to take the measurements and took my measurement at the waist to be 37". Now I wear nothing but 34" in the waist, as anything larger will fall off. My question is; how is it that I wear a waist measurement of 34" but the overall waist 37"? How do they measure this when making pants? I was thinking about purchasing some MTM pants, and now I'm wondering which measurement to use. Anyone have any suggestions?
